React Native Requires Chilkat v11.0.0+

Convert PEM to JKS (Java KeyStore)

See more PEM Examples

Converts a PEM containing private key(s) and certificates into a JKS (Java KeyStore) formatted file. React Native

import { JavaKeyStore, Pem } from '@chilkat/react-native'

function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const pem = new Pem();

  // Load the PEM from a file.
  // If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.
  const password = 'myPassword';
  try {
    pem.loadPemFile('../myPemFiles/myPem.pem', password);
  } catch {
    console.log(pem.lastErrorText);
    return;
  }

  // Note: If the app already has the PEM pre-loaded in a string variable, then load it 
  // by calling LoadPem instead.  
  const pemContent = '... the PEM contents ...';
  pem.loadPem(pemContent, password);
  // Check for success as before..

  // Convert to a JavaKeyStore object.
  // The alias, if a non-empty string, will be applied to the 1st private key or 
  // certificate.  All other keys and/or certificates will be assigned an auto-generated
  // alias.
  const alias = 'anything_I_want_here';

  // This is the passord that will be required to access the created JKS.
  const jksPassword = 'myJksSecret';
  const jks = new JavaKeyStore();
  try {
    pem.toJksObj(alias, jksPassword, jks);
  } catch {
    console.log(pem.lastErrorText);
    return;
  }

  // Save the JKS to a file.  The password passed here is used for the keyed hash of the
  // entire JKS file.  This may be different (if desired) than the password for individual private keys
  // contained within the JKS.  
  try {
    jks.toFile(jksPassword, '../myJksFiles/myJks.jks');
  } catch {
    console.log(jks.lastErrorText);
    return;
  }
